Airtac BSE Clamp Standard Cylinder BSE32X125S
The AirTAC Airtac BSE Clamp Standard Cylinder BSE32X125S is a genuine double-acting ISO 15552 cylinder with an integrated spring-applied, air-released ROD LOCK. If air is cut or an E-stop is hit, the collet clamps the Ø12mm rod and holds up to 600 N in either direction — no drift. Ø32mm bore, 125mm stroke, PT1/8 cylinder ports, G1/8 lock-release port.

About the Airtac BSE Clamp Standard Cylinder BSE32X125S
The AirTAC BSE32X125S is a double-acting, single-rod ISO 15552 profile cylinder featuring an integrated spring-applied, air-released rod lock. It delivers a 600 N bidirectional static holding force to prevent drift during air loss or E-stop events. Operating pressure is capped at 0.7 MPa, and the standard cylinder port is PT1/8.
This 32 mm bore unit includes a -S magnet for position sensing and uses a separate G1/8 port to unlock the collet. The lock is a holding device, not a dynamic brake; it must engage only after the rod fully stops. You must balance piston pressures and allow at least 0.5 s before releasing the lock for safe motion.
Rod Lock — 600 N Static Holding (Ø32mm)
A spring clamps the collet onto the rod, so the Airtac BSE Clamp Standard Cylinder BSE32X125S holds its position in both directions when air is lost, exhausted or an E-stop trips. Apply 0.15–0.7 MPa to the G1/8 release port to unlock. Engage the lock only after the rod has stopped (it is not a dynamic brake), and release only when the pressures on both sides of the piston are balanced. Allow at least 0.5 s for full release before moving.

Specifications follow the official AirTAC BSE datasheet. The lock uses the SE standard body; SE mounting accessories fit BSE except FTC. Port options: PT (standard) / G (BSPP); lock-release port is G1/8.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa (max) | 563 N | — |
| Max drive (@0.7 MPa) | 57 kgf | |
Drive force is separate from the 600 N static holding force of the lock. BSE operates up to 0.7 MPa. Size with a safety margin.

Where the Airtac BSE Clamp Standard Cylinder BSE32X125S Is Used
PCB Lift Stations
Holds a 600 N vertical electronics lifting stage firmly in place during an air pressure drop, preventing delicate board crashes.
Light Tool Clamping
Secures a small pneumatic gripper arm with 600 N of force, ensuring the clamped part does not slip if the main air supply is exhausted.
Package Diverters
Locks a 125 mm stroke diverter gate in position during an E-stop, keeping the conveyor lane alignment rigid without live air.
Is the Airtac BSE Clamp Standard Cylinder BSE32X125S the Right Cylinder?
Verify your suspended load requires no more than the 600 N static holding force. If you need less drive, no smaller BSE bore exists. If you need more holding or drive force, step up to the 40 mm bore, which provides 628 N push at 0.5 MPa and a 900 N hold. Always engage the lock only after the rod stops, and release it only when both sides are pressure-balanced.
For exact replacements, match the 32 mm bore, 125 mm stroke, PT1/8 port, and -S magnet. The 125 mm stroke is under 300 mm, so standard guide rules apply, but always minimize side loads on the rod. SE mounting accessories fit this body, except FTC.
Quick checklist
- ✓ Load to hold ≤ 600 N?
- ✓ Fail-safe hold on air loss / E-stop needed
- ✓ Lock engaged only when stopped
- ✓ G1/8 release-air line available
- ✓ Magnet (-S) for CMSE/DMSE sensors?
Installation & Safety Notes
- check Engage the lock only after the rod has stopped — not as a dynamic brake.
- check Release only when both piston sides are pressure-balanced.
- check Allow ≥0.5 s for full release before commanding motion.
- check Feed the G1/8 release port with 0.15–0.7 MPa clean air.
- check Add safety-rated controls for man-rated / overhead loads.
- check Use SE mounting accessories (FTC excepted).
Airtac BSE Clamp Standard Cylinder BSE32X125S FAQ
The integrated collet lock is spring-applied and air-released, providing a 600 N bidirectional static hold with no live air. The drive force is separate: 402 N push and 345 N pull at 0.5 MPa, 563 N push at 0.7 MPa, with a maximum drive of 57 kgf.
You must supply 0.15-0.7 MPa to the separate G1/8 release port. Ensure the pressures on both sides of the piston are balanced first, then allow at least 0.5 s for full release before moving the rod to prevent dynamic braking damage.
